Abstract
An object is to acquire a head-related transfer function reproducing features of a head-related transfer function of a listener without actually measuring the head-related transfer function of the listener. A head-related transfer function generator includes: acquiring data that represents an actually measured head-related impulse response of sound waves arriving at external auditory meatus entrances of a listener for training; calculating an initial head-related impulse response by applying a window function to the actually measured head-related impulse response and generating data representing an early head-related transfer function by performing a Fourier transform on the initial head-related impulse response; dividing the early head-related transfer function into a plurality of frequency bands; and executing a process of extracting a peak or a notch on the basis of curvature of the early head-related transfer function and a process of determining a relative amplitude for each of the plurality of frequency bands and generating data representing a modeled head-related transfer function of the listener for training by interpolating points representing the relative amplitudes.
